Nowadays, researches focused towards the beneficial health effects that some dietary components may possess, have raised great attention. Among the bioactivities related to the ingestion of healthy dietary compounds, their possible anti-proliferative activity is gaining importance due to the relevance of cancer as one of the most frequent death causes at present. The possibility of preventing processes related to cancer development thanks to particular diet components, such as phenolic compounds, has opened an important research field. However, the particular mechanisms of action through which these components may exert their anti-proliferative activity in-vivo are greatly unknown. This is mainly due to the fact that common in-vitro assays employed nowadays do not take into consideration important parameters related to digestion, absorption, metabolism and modification of those components after their ingestion. Therefore, it is of utmost importance to precisely know the physiological forms derived from the ingested phenolic compounds that can be actually found in the organism as well as their bioactivity, considering that these chemical structures would be those that could in reality exert a beneficial health effect in-vivo. In this regard, the appliation of Foodomics-based approaches may be of great usefulness to unravel the processes taking place in-vivo. The main objective of this project proposal is to study the anti-proliferative activity and molecular mechanisms of action of dietary phenolics from rosemary and different algae species as well as from their corresponding in-vivo metabolic and degradation products against human colon cancer cells. The selection of these two natural matrices is based on the numerous scientific references existing on the anti-proliferative potential of rosemary polyphenols, although, how these components exert their activity in-vivo is still in doubt (e.g., the bioavailability of these compounds as well as if their anti-proliferative activity is actually related to their metabolites/catabolites generated in-vivo is unknown). Moreover, algae are selected due to the huge potential associated to those organisms as an unexplored novel source of anti-proliferative compounds. In this project, a new strategy which application will allow obtaining a deeper knowledge on how dietary components may exert an anti-proliferative activity against human colon cancer cells is proposed, using the ingestion of rosemary and algae polyphenols as model. Particularly, to develop this new strategy, the use of advanced environmentally friendly extraction techniques is combined with the employment of a dynamic gastrointestinal simulation system and with the use of different in-vitro assays using cell cultures, as well as with powerful Foodomics tools (metabolomics and transcriptomics) and a short pilot intervention study in order to confirm the observations previously made at an in-vitro level. The successful application of this new methodology will provide with a deeper understanding on the phenomena taking place during the ingestion of the studied compounds (digestion, metabolism, absorption and interaction with gut microbiota) and how those phenomena influence the anti-proliferative activity of the native dietary components.
